A crown for a bottle or other container has a top portion and an annular skirt that descends contiguously from the top portion. An opener assembly and an arrangement of frangible scoring lines on the crown allow for ease of opening the bottle or container. Corrugated embodiments provide material strengthening for a reduced gauge crown.

A pull tab crown for a bottle or other container provides an opener secured to the top of the crown. The crown has an annular skirt with an annular edge. Score lines extend from the opener assembly to the skirt. One of the score lines is curvilinear and terminates at the annular edge. A second score line has a segment that extends from the opener assembly to an endpoint substantially spaced from the bottom annular edge of the skirt.

A crown, for a medical vial opening, has a top portion and a skirt surrounding the top portion. The skirt terminates at a lower edge defined in a first horizontal plane. An opener assembly is mounted to a portion of the top. A first scoring line extends from the portion of the top to which the opener assembly is mounted to the lower edge of the skirt in a continuous radial direction, and a second scoring line provides an upper radial segment extending from the opener assembly to the skirt along a radial axis, and a lower annular segment that extends circumferentially along the skirt in an annular direction and extending from a terminus of the upper radial segment. The lower annular segment is defined in a second horizontal plane equidistant to the first horizontal plane associated with the lower edge of the skirt.

A reduced gauged crown for a container opening includes a corrugated panel portion such that the corrugation strengthens the crown material and allows less material to be used for the crown than would be used for an uncorrugated bottle cap.

A pull-off closure for containers having an opening whose end portion defines an annular collar projecting externally; the closure including: an upper portion shaped in the form of a shell having an upper face from which extends a collar, which can be turned over to abut on the annular collar of the container, during capping of the container, the upper face and the collar forming, at their connection, an annular edge; lines of weakness formed on the upper face and on the collar forming an opening strip which extends in a tab extending beyond the collar; a gripping element which can be associated with the tab, wherein the lines of weakness extend on the collar outside the annular edge.

The present utility model relates to a structural arrangement for a bottle cap, belonging to the technical field of packaging accessories in general, more particularly to a cap for beverage bottles, such as beer, water, soft drinks, or any other drink or product for which the bottle is used as a packaging container, producing convenient, safe and functional results which are very advantageous. The innovation comprises a cap (10) to which an opening device (30) is coupled by a clip in the central top part. The cap (10) has a breaking zone (101) and a central hole (102) for coupling the clip (20) which links the cap (10) to the cross-shaped opening device (30) which forms four levers (302) with protruding projections (303) on the top surface and with a piercing point/tooth (304) on the underside of each lever (302), which pierces the breaking zone (101), allowing the inner pressure to escape and thus making it easier to remove the cap (10) with the lever formed at the opposite end.
